AIR CLEANER.

Application filed May 13, 1921. Serial No. 469,158. r

The present invention relates to a device for use in connection with a carbureter, particularly a carbureter intended for two-cycle type of engine, and the object of the device is first to filter all incoming air which passes through the carbureter, and secondly, to afford a vaporizing device for the purpose of supply carbureted air when the engine is to be started.

Reference should be had to the accom-v panying drawing forming a part' of this specification in which Fig. 1 is a sectional elevation; Fig. 2 is a bottom plan view; Fig. 3 is a plan view of a screen forming part of the device.

The device forming the invention comprises a body member 1 which is preferably made to have a flaring portion and a threaded neck portion 2 by which the device may be secured to a carbureter. Within the flaring body portion there is a mass of hair or similar material which is represented at 3, the hair being confined between a lower screen member 4: which is secured at its edge to the outer edge of the flaring portion 1. Above the screen 4 is a second screen 5 of smaller diameter and it w fits within the flaring wall portion,-lies above the mass of hair and serves to confine same.

The device thus far explained is very useful as an air filter, particularly when the hair is coated with some unvolatile oily substance. Air which may pass through the device will have the dust taken from it by contact with the oily hair so that air delivered to the carbureter will be free from grit or dust.

- Additionally the device may have incorporated with it an additional member which in combination with a portion of the carbureter may be used to preliminarily operate the fuel inlet valve of the carbureter to discharge a certain amount of gasoline or similar fluid fuel onto the hair which is confined within the device. Thereafter when the engine isturned over so as to draw in air through the carbureter, the air so, drawnin atomizes the gasoline and carries it along to the engine, thus supplying a mixture of air and gasoline in atomized condition which is in suitable condition for ignition and starting of the engine. j

In the drawin the device is shown as attached to a car ureter. which comprises a.

by the needle valve 12. The admission of.

gasoline to the chambered member 6 is also controlled by a movement of the valve 8, the valve when in closed position covering the gasoline feed duct as clearly shown in i uch a carburetor is particularly adapted for use with a two cycle engine, and when suction is produced within the chambered member 6, the valve 8 is lifted, allowing the entrance of air which carries with it gasoline which is atomized by the passage of the air past the gasoline feed duct.

The valve 8 has a valve rod or pin 8 which extends below the valve.

Located substantially central with respect to the screens 4 and 5 is a rod 13 which has a flattened head 14. This head is so positioned that when. the rod 13 is raised it will contact with the stem 8 and result in elevating the valve 8.

It usually hap ens in carbureters of the type under consi eration, that when theengine is stopped a limited quantity of gasoline will accumulate in the chambered member 6 and will be retained in the chamber because the valve 8 remains seated. Displacement of the valve 8 b actuating the rod 13 prior to starting the engine will therefore permit gasoline to flow onto the It will be seen that when the engine is running all the air which enters the carbureter must pass throughthe mass of hair and all grit and dust will be removed therefrom.

It will be obvious that the precise construction by which gasoline is introduced onto the mass of hair for starting purposes is but illustrative andthe invention is not confined to the particular form shown.
